How to get current action?

by

I am developing custom registration form. Is it possible to get current action (comment adding or user registration) in function? For example i am using:

add_filter('preprocess_comment', 'checkQuestion');
add_filter('registration_errors', 'checkQuestion', 10, 3);

So, from function checkQuestion i need somehow to know from what action it was called?

You can simply use current_filter() WordPress function.
